CLINTON B. REP]? AND IRA LEE COCHEANE, OF NEW YORK, N. Y.

WINDOW.

Application filed June 19, 1911.

1/ '0 all to 710m it may concern Be it known that we, CLINTON B. Rnrr and IRA LEE COOHRANE, a citizen of the United States, and a subject of the King of Great Brita n, respectively, and residing, respectively, at the borough of Manhattan, in the city, county, and State of New York, and at the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Windows, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

Our invention relates to windows, and more particularly to a type thereof embodying therein combined sliding and swinging sashes.

The main object of our invention is to provide a window of this character wherein that portion of the structure carrying the lights of glass may be swung into the room for purposes of cleaning, without interfering with the parting strips carried by the stiles and sills, while securing weather proof joints about the movableportions of the window.

A further object is to provide a window embodying sashes which may be swung inwardly, the construction and arrangement of the movable parts of which will be such as to adapt them to use with ordinary window frames.

A still further object is to provide a window wherein the sashes carrying the lights of glass may be swung into the room separately or together, the upper sash, when both are swung in together, moving through the opening left by the movement of the lower sash, the construction being such as not to require a substantial dissimilarity in the sashes carrying the lights of glass.

A still further object is to provide the upper or outer frame with a swinging sash adapted to retain the light of glass which will open freely, passing through the open ing in the lower frame and yet when closed will form a weatherproof oint. And a still further object is to provide a window which will be simple in design and inexpensive to produce, while not sacrificing the area of the lights contained therein.

The invention consists in such novel features of construction and combination of parts as are hereinafter set forth and de- Specification of Letters Patent.

scribed, and more particularly pointed out in the claim hereto appended.

Referring to the drawings :Figure 1 is an inside elevation of a window embodying our invention, sections thereof being broken away to disclose details of construction; Fig. 2 is a vertical section on the line 22 of Fig. 1 but upon an enlarged scale; Fig. 3 is a horizontal section through the lower portion of the window when both sashes are lowered, the operation of the supplemental sashes being shown in dotted lines; and Fig. 4 is a perspective view in section of the upper portion of the upper sash showing the manner of rabbeting the inain sash to secure the weather proof joint.

Like letters refer to like parts throughout all of the several views.

In the embodiment of our invention shown in the drawings, 10 indicates an ordinary window frame having vertical run ways on the stiles, said frame and run ways being of the ordinary construction and arrangement. Slidably mounted in said run ways are upper and lower supplemental frames 11 and 12 provided with the ordinary counterweights (not shown) and sash cords 13. Each frame 11 and 12 has pivotally mounted therein a swinging sash containing a light or lights of glass 1& and 15. These sashes are mounted upon vertical pivots and the detailed arrangement and construction of the parts is such that the upper sash may swing through the lower so that both sides of the lights of glass may. be exposed within the room to permit the cleaning thereof without endangering the life of the worker.

To secure the desired result, it is necessary to construct each sash with due relation to the other, in order to secure the proper cooperation of parts and a weather proof structure. e will therefore first describe the construction of each sash frame in detail and then point out more specifically the relative importance of such detail.

The lower sash frame 12 is provided on the inside thereof, on both the vertical and the horizontal rails, with an inwardly presented rabbet 16, and mounted therein by means of hinges 17, having vertical pivots, is the sash 18 provided with a rabbet 19 adapted to cooperate with the rabbet 16 in forming a tight, weatherproof joint between the supplemental sash frame and its swinging sash. A latch device 20 is provided upon said lower sash to hold it in the closed position.

It will be observed that the sash slides freely with the supplemental sash frame and that when closed, it engages the said supplemental sash frame upon both the side and the top and bottom rails in a manner to form a unitary sash construction while permitting said supplemental sash to be opened inwardly into a room and leaving the supplemental sash frame properly braced so as to avoid any displacement of parts when the sash is so opened. The top rail of the supplemental sash frame is provided with the ordinary bevel 21 to secure a tight fit be tween the upper and the lower sashes when the window is closed.

The upper sash comprises the supplemental sash frame 11 having a lower rail with out obstruction of any kind thereon. The top rail is provided with a rabbet 22 presented inwardly and extending from one side rail to a point adjacent to, but spaced away from the other, that portion of the said top rail between the end of said rabbet 22 and the. other side rail being provided with an outwardly presented rabbet 2i along its entire length and the other side rail is provided with an inwardly presented rabbet 25 throughout its entire length.

The rails of the top supplemental frame are slightly wider than those of the lower supplemental frame to provide the desired clearance in the lower frame for the passage of the upper swinging sash.

The upper sash frame 11 has pivotally mounted therein by means of pivots offset relatively to the side rail of said frame, a swinging sash 26 which carries the light or lights of glass 14. By offsetting the pivots for said sash 26, said sash is permitted to swing parallel with the lower sash 18 While at the same time permitting the sash frames to be of substantially the same dimensions. The side rail of the sash 26 adjacent to the point of pivotal support is formed with an inwardly presented rabbet 27 adapted to cooperate with the rabbet 24 upon the main sash frame 11, and the other side rail is provided with an outwardly presented rabbet 28 cooperating with the rabbet 25, thus making the supplemental sashes along both side rails thereof, weatherproof.

The bottom of the lower rail of the sash 26 is perfectly smooth and has a sliding fit with the lower rail of the frame 11, being provided however, with an inwardly presented bevel 29 cooperating with the bevel. 21 upon the lower frame 12.

The top rail of the sash 26 is provided with an outwardly presented rabbet upon one side of the point of pivotal support of said sash, and upon the inner edge of the said rail, and with an inwardly presented rabbet upon the other side of said point of pivotal support and upon the outer edge of said rail. It will thus be observed that although said sash 26 swings upon pivots spaced away from the edge thereof, the arrangement of rabbets upon the top rail thereof is such as to permit it to swing freely and at the same time when it is closed have a weatherproof joint.

Carried by the bottom rail of the sash 26 is a plate 30 carrying thereon a pivot pin 31 adapted to be seated in a socket 32 carried by the supplemental frame 11. Owing to the stability of the structure of the lower rails of the supplemental frame,

and its swinging sash this pivot construction will be found to besatisfactory. The upper pivots, however, are at a point where the upper rail of the supplemental frame has been weakened by the formation of the oppositely disposed rabbets and to reinforce the main frame and the rabbet 24, we mount thereon a face plate 33 carrying a pivot pin 34 which enters a socket in the plate 35 carried by the top rail of the sash 26. The pivot 34 is in alinement with the pivot 31 and the sash 26 turns freely upon these two pivots. The use of the plates 33 and 35 imparts the desired stability to the main and supplemental frames at this point and at the same time afiords a hinge connection which may be readily applied. This construction also avoids unnecessary mortising and simplifies,- and lessens the cost of production of,'the window.

To further stiffen. the main frame 11, we provide metallic corner plates 36 which prevent such a racking of the frame as would result in a binding of the pivot or in a loss of fit between the main and the supplemental sash frames.

It will be observed by the foregoing that the main frames 11 and 12 are complete rectangular frames sliding in the window stiles in the usual manner, and that said frames form an accurate rigid support for the sashes and would under ordinary condi tions of use not be subjected to such strains as would tend to interfere with the free operation of the sashes.

When the window is closed, the cooperating bottom rail of the sash 26 and the top rail of the lower supplemental frame 12, serve to hold the said sash 26 in the closed position, and as the window is opened or closed, the engagement of the side rails of the sash 26 with those of the supplemental frame 18 will prevent the accidental opening ed in the same direction on all sides of said frame, permitting said sash to swing freely into the room upon pivots arranged adjacent to the inner face of the adjoining parts of the said two frames. The lower sash having thus been opened, clearance is provided through which the upper sash 26 may be swung inwardly upon its pivots 31 and 34. As the upper sash is thus swung, the bottom rail thereof moves freely over the bottom rail of the supplemental frame 11, and the right hand side rail and the top rail adjacent thereto swing inwardly away from the rabbets upon the frame 11. The other side rail, however, and the top rail adjacent thereto swing outwardly, thus necessitating the use of side rails having oppositely presented rabbets and a top rail, the portion of which upon one side of its pivots is presented inwardly and the portion of which upon the other side of said pivots is presented outwardly. It will thus be observed that both windows may be freely swung inwardly when in the lowered position, thus exposing within a room the outside of the lights of glass mounted therein.

To restore the windows to the normal position, it is merely necessary to close them, the various rabbets cooperating to form a weatherproof joint between each main sash and the supplemental sash carried thereby.

It will be noted that the ordinary window frame and the ordinary arrangement of sash. cords and counter weights may be used with a window constructed as herein described, and that so far as the completely assembled window is concerned, the conditions are substantially the same as in the ordinary window.

As above pointed out, it is necessary that the rails of the top supplemental frame be of substantially the same dimensions as the lower frame including the rabbets thereon, in order to provide the proper clearance for the passage of the upper sash through said frame. This will necessitate a slightly smaller sash upon the upper supplemental frame, although if desired, the rails of the lower frame may be made wider so as to make the lights of glass of the two sashes of the same dimensions.

l/Ve are aware that heretofore the use of sliding and swinging sash frames has been suggested and it is not our intention to claim such broadly. e believe, however, that the detailed construction herein described is novel, and we do not intend to limit ourselves to the precise details of construction shown in the accompanying drawings, it being apparent that such may be varied without departing from the spirit or scope of the invention.

Having described our invention, what we claim as new and desire to have protected by Letters Patent, is

A window embodying therein an upper and a lower rectangular sliding supplemental frame, a horizontally swinging sash hinged at one edge thereof to said lower supplemental frame, a sash carried by the upper supplemental frame, vertically extending pivotal connections between said upper frame and its sash arranged intermediate the side rails of said supplemental frame, whereby said last named sash is permitted to swing freely through the lower supplemental frame.

In witness whereof, we have hereunto affixed our signatures, in the presence of two witnesses, this 15th day of June, 1911.
